Power Dissipation
Specifications
Use the following table to size an enclosure and calculate required
ventilation for your 8720MC system.
1
The open packaged drive ambient operating temperature is 50°C (122° F). The cabinet enclosure should be
designed to provide an operating temperature that does not exceed 50°C (122° F) in worst case ambient
conditions.
2
Drive rating is based on altitudes of 1000 meters (3000 feet) or less. If installed at a higher altitude, derate the
drive.
